Portland Bureau of Parks & RecreationThe Portland Bureau of Parks & Recreation offered a photo of Delta Park as an example of damage that prompted the bureau to close all grass fields at least through Tuesday.

The bureau said the recent wet, cold weather has left the fields damaged and unsafe. The fields include all those for soccer, rugby, kickball, lacrosse and ultimate Frisbee. The bureau will work with leagues to place some games at the Rob Strasser Memorial's or Rieke Elementary's synthetic fields.

The bureau will monitor the fields in coming days and post information at portlandparks.org, with an update by 3 p.m. Tuesday. Further damage to the fields could lead to a long-term closure, the bureau said in a news release.
